Question

我正在尝试使用fpdf在php表单中单击生成多个（在群集中）pdf报告。

test_center是单独报告的集群。单击提交按钮时，它将调用fpdf的php文件。我的代码还没有工作。

到目前为止，在我的php中：

<?php
$program="select distinct test_center  from sa_sase_result where school_year = '$content' ";
$prog=mysql_query($program);
while($row = mysql_fetch_array($prog))
{
    echo '<option>' .$row['test_center'] . '</option>';      
}  

$message = null;

if($_SERVER["REQUEST_METHOD"] == "POST") { 
    if(!isset($_POST['depchair'])) {

    } else if($_POST['depchair']=="") {

    } else {            
        $input_depchair = addslashes($_POST['depchair']);                       

        $input_depchair = addslashes($_POST['depchair']);
        $pro_email="select control_no  from sa_student_infoe y where y.test_center = '$input_depchair'";
        $pro_address=mysql_query($pro_email);

        $address = mysql_result($pro_address, 0);
    }                   
}
?>

编辑：这是generate_pdf.php文件。

<?php

require('fpdf/fpdf.php');


 mysql_connect("localhost", "root", "1234") or die(mysql_error()); 
 mysql_select_db("final") or die(mysql_error()); 

 $query = "SELECT * FROM sa_student_infoe, sa_student_edubg, sa_sase_result, sa_accounts";
      $result = mysql_query($query) or die(mysql_error());
      while($row = mysql_fetch_array($result, MYSQL_BOTH)){
      $control_no[] = $row['control_no'];
      $surname[] = $row['surname'];

JS：

$("#id_of_generate_it_button").click(function () {
    var N = 10;// ten pdf files will be generated and stored to the disk
    for (i = 0; i < N; i++) {// 'the loop' -- walk thru all parallel generation processes connected to the event
        parameter = N;// just to definite each single generated file
        $.get("generate.php?q=parameter", function (data) {// start the ajax process to generate single document
                                                           // ?q=parameter i wrote just for passing to the php file some dependent parameter for each single file 
            // pdf #i generated
        });
    }// end for parallel generating N pdf files to the disk
});//end click

generate.php中的

：

$query = "SELECT * FROM sa_student_infoe, sa_student_edubg, sa_sase_result, sa_accounts WHERE some_field = ' . $_REQUEST['q'] . '";// single record from all
